This is a known bug in lm_sensors 2.9.0, which has since been fixed in
The reason why you did not have the error at first is that the bmcsensors
module is only compiled if the underlying kernel has IPMI support. Maybe
your original kernel didn't have. I never included IPMI support myself
so far (I don't need it) which is why the compilation error slipped
into 2.9.0 without me noticing. Now I do include it but just in order to
find out compilation errors before we release.

That's OK then, as you don't really need that driver anyway.

Yeah, I remember similar reports about the CVS version. This was caused
by a misproperly configured clock. If your clock is set in the past,
make is not able to satisfy dependancies and might loop forever. When
this happens, just check that the clock is correct and that no file in
the lm_sensors tree has time in the future.
Hope that helps,
